 ing off a short axis-cylinder process at right angles 

 to the surface. C, Mast-, leukocytes containing 

 coarse basophile granules. They are occasionally 

 present in the peripheral circulation as the result of 

 certain pathologic influences, but are totally foreign to 

 the normal blood of man. They are commonly found 

 in the splenomedullary type of leukemia. The gran- 

 ules of the mast-cell show an intense affinity for basic 

 anilin dyes, toward which they react metachroinat- 

 ically. In view of their distinctive behavior toward 

 selective stains for mucin, Harris suggests for the mast- 



cell the term mucinoblast. [DaCosta.] C.s, Mastoid.
